What Amoxicillin Treats

Broad-spectrum coverage for hot-spot skin infections, ear infections, respiratory issues, bite-wound bacteria and UTIs. The active ingredient—amoxicillin trihydrate—reaches therapeutic blood levels fast and is safe for most adult dogs when dosed correctly.

Weight-Based Dosage Guide

Standard guideline: 5 mg per lb of body weight every 12 hours. Use our Dosage Calculator for exact mg and capsule count. Example:

25 lb dog → 125 mg (½ × 250 mg capsule) twice daily
50 lb dog → 250 mg (1 × 250 mg capsule) twice daily
90 lb dog → 450 mg (≈1 × 500 mg capsule) twice daily

Storage & Safety Tips

Store bottles at 68–77 °F (20–25 °C), away from moisture.
Give with or without food; a small treat masks any taste.
Finish the full course—stopping early promotes resistant bacteria.
Watch for rare side-effects (soft stool, rash). Contact a vet if severe.

Can I give human amoxicillin 500 mg to my dog?

The molecule is identical, but veterinary-labeled capsules provide weight charts, flavoring and liability coverage. Our dog-specific bottles are safer.

Is a prescription really not required?

Correct—companion-animal antibiotics may be sold OTC when labeled for canine use. Always follow dosage guidelines and consult a vet for complex cases.
